Hello and welcome to Eurosport's live commentary from the Champions League Round of 16 second leg between Juventus and FC Porto. This is Nick Royle (@nickaroyle) taking you through all the action from the Juventus Stadium.

Brahimi sets up Andre Andre, but his pass towards Andre Silva is overhit and the Porto chance is wasted.

It's a very tepid start to the game so far. Felipe then is able to head clear Alves' cross under pressure from Higuain.

CHANCE: Mandzukic gets a bullet header onto Cuadrado's cross to the far post, but his effort is straight at Casillas.

Dybala is caught in midfield by Andre, Sandro's pass down the line is cut out by Maxi Pereira.

Marcano is across to cut off the run of Dybala, and Porto can clear the follow-up Marchisio cross.

Some better build-up play by Juventus. Marchisio is starting to gain a foothold in the game in midfield.

Dybala and Cuadrado link down the right, but Danilo can clear and Silva is caught by Dani Alves when he attempts to flick clear the second ball.

Layun gets his own back on Cuadrado with a late tackle near the halfway line. Juventus have started this match quite slowly - they obviously fancy their chances on the break though.

Brahimi is unable to control a Danilo cross from the right near the Juve penalty spot.

Some good possession from the visitors. Brahimi seems the focal point down the left flank.

Brahimi's poor free-kick is easily cleared by the Juventus defence. Layun is still limping, and bleeding, following that Cuadrado foul.

Cuadrado gets a yellow card for a lunging tackle on Layun on the right-hand side of the Juve box.

SAVE: Soares shoots and forces a workaday save from Buffon. Danilo, who started the move, looks annoyed that he didn't get the ball back from the Brazilian striker.

Brahimi sees an angled ball towards Soares drift just beyond the Porto striker. But that was a good move from the visitors, with some nice build-up play by Andre Silva.

Mandzukic is fouled by Felipe just near the centre circle. Porto definitely trying to discomfort the home side in the opening stages.

Cuadrado wins a free-kick down the right flank on the halfway line. The home fans are in good voice, as Dybala sees a snapshot from Mandzukic's cushioned header whistle just wide.

A period of keepball for Porto, until Soares is bundled off the ball by Benatia on the edge of the area. Soares is on the floor, protesting to the Romanian referee that he was fouled.

CHANCE: Dybala shoots wide from the right-hand side of the box from Sandro's ball across the box. Mandzukic and Higuain are furious the Argentine didn't cut the ball across the area rather than shoot.

Oliver Torres and Danilo look like the holding players for Porto, as they try and close down Juve early. Felipe is across to the right channel to clear, then Higuain sees an optimistic header from Alves' cross whistle wide.

Juventus are in their third kit of all white, while Porto play in their third-choice kit of black shirts and black shorts. Porto kick off from right to left.
